others and refer to it; or, on the other hand, there are several things
that have the whole set of their properties in common, in which case it
is quite impossible to indicate one of them. For if there is nothing to
distinguish a thing, I cannot distinguish it, since otherwise it would
be distinguished after all.

2.024 The substance is what subsists independently of what is the case.

2.025 It is form and content.

2.0251 Space, time, colour (being coloured) are forms of objects.

2.026 There must be objects, if the world is to have unalterable form.

2.027 Objects, the unalterable, and the subsistent are one and the same.

2.0271 Objects are what is unalterable and subsistent; their
configuration is what is changing and unstable.

2.0272 The configuration of objects produces states of affairs.

2.03 In a state of affairs objects fit into one another like the links
of a chain.

2.031 In a state of affairs objects stand in a determinate relation to
one another.

2.032 The determinate way in which objects are connected in a state of
affairs is the structure of the state of affairs.

2.033 Form is the possibility of structure.

2.034 The structure of a fact consists of the structures of states of
affairs.

2.04 The totality of existing states of affairs is the world.

2.05 The totality of existing states of affairs also determines which
states of affairs do not exist.

2.06 The existence and non-existence of states of affairs is reality.
(We call the existence of states of affairs a positive fact, and their
non-existence a negative fact.)

2.061 States of affairs are independent of one another.

2.062 From the existence or non-existence of one state of affairs it is
impossible to infer the existence or non-existence of another.

2.063 The sum-total of reality is the world.

2.1 We picture facts to ourselves.

2.11 A picture presents a situation in logical space, the existence and
non-existence of states of affairs.

2.12 A picture is a model of reality.

2.13 In a picture objects have the elements of the picture corresponding
to them.

2.131 In a picture the elements of the picture are the representatives
of objects.

2.14 What constitutes a picture is that its elements are related to one
another in a determinate way.

2.141 A picture is a fact.

2.15 The fact that the elements of a picture are related to one another
in a determinate wa
